SERVICING AND MAINTENANCE
SCHEDULED SERVICING — NON-SRT
Your vehicle is equipped with an automatic oil
change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required”
message is displayed. Severe Operating
Conditions can cause the change oil message
to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off road environment or
is operated predominately at idle or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:Check engine oil level
Check windshield washer fluid level
Check the tire inflation pressures and look
for unusual wear or damage
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed.
Check function of all interior and exterior
lights

CHECKING OIL LEVEL
To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals, such as every fuel stop. The best time
to check the engine oil level is about five
minutes after a fully warmed up engine is shut
off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Always maintain the oil level within
the SAFE zone on the dipstick. Adding one quart
of oil when the reading is at the bottom of the
SAFE zone will result in a reading at the top of
the safe zone on these engines.
ADDING WASHER FLUID
The instrument cluster display will indicate
when the washer fluid level is low. When the
sensor detects a low fluid level, the windshield
will light on the vehicle graphic outline and the
“WASHER FLUID LOW” message will be
displayed.
The fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will
help blade performance. To prevent freeze-up
of your windshield washer system in cold
weather, select a solution or mixture that meets
or exceeds the temperature range of your
climate. This rating information can be found on
most washer fluid containers.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a
maintenance-free battery. Water will never have
to be added, nor is periodic maintenance
required.
CAUTION!
Overfilling or underfilling will cause oil
aeration or loss of oil pressure. This could
damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water. Refer to “Jump
Starting Procedure” in “In Case Of Emer -
gency” for further information.

Change Engine Oil — SRT (If Equipped)
The oil change indicator system will remind you
that it is time to take your vehicle in for
scheduled maintenance. Refer to “Scheduled
Servicing” for further information.
NOTE:
Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km) or
6 months, whichever occurs first.
Engine Oil Selection — Non-SRT (If
Equipped)
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils
that are API Certified and meet the
requirements of FCA Material Standard
MS-6395.
NOTE:
Hemi engines (5.7L) at times can tick right after
startup and then quiet down after approxi -
mately 30 seconds. This is normal and will not
harm the engine. This characteristic can be
caused by short drive cycles. For example, if the
vehicle is started then shut off after driving a
short distance. Upon restarting, you may experience a ticking
sound. Other causes could be if the vehicle is
unused for an extended period of time, incor
-
rect oil, extended oil changes or extended
idling. If the engine continues to tick or if the
Malfunction Indicator Light (MIL) comes on, see
the nearest authorized dealer.
Engine Oil Selection — SRT (If Equipped)
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends full synthetic
engine oils that meet the American Petroleum
Institute (API) categories of SN.
The manufacturer recommends the use of
Pennzoil Ultra 0W-40 engine or equivalent
Mopar oil meeting the FCA Material Standard
MS-12633 for use in all operating
temperatures.
The engine oil filler cap also shows the
recommended engine oil viscosity for your
engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in this
section for further information. NOTE:

CAUTION!
Do not use chemical flushes in your engine oil
as the chemicals can damage your engine.
Such damage is not covered by the New
Vehicle Limited Warranty.7

NOTE:
Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in
improper operation of the Fuel Saver Tech
-
nology. Refer to “Fuel Saver Technology – If
Equipped” in “Starting And Operating” for
further information.

BRAKE SYSTEM
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked whenever the vehicle is serviced, or
immediately if the brake system warning light is
on. If necessary, add fluid to bring level within
the designated marks on the side of the
reservoir of the brake master cylinder. Be sure
to clean the top of the master cylinder area
before removing cap. With disc brakes, fluid level can be expected to
fall as the brake pads wear. Brake fluid level
should be checked when pads are replaced. If
the brake fluid is abnormally low, check the
system for leaks.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri
-
cants” in “Technical Specifications” for
further information. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle
is also identified on the original factory
installed hydraulic master cylinder
reservoir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
a open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
